Principal Edwards Magic Theatre
Michael "Harry" Housman
Principal Edwards Magic Theatre were a UK band who had their own dedicated Light Show which wasn't all that common back then.

Later on Harry started to relate the content of the songs to photos and black and white images, whereas before it was pretty arbitrary! And we got more heavily into stage lighting.

If you can help with more information about this Light Show we would love to hear from you.
